When Stanley brings up divorce, his Italian-speaking wife recognizes the word and goes into a whole spiel in which she mentions actor Marcello Mastroianni, who starred in this other comedy about murdering one's wife.
Stan (Lemmon) sees his wife (Lisi) in bed in the morning with curlers in her hair. He imagines her in the same position as Tilly Soames when she was murdered by Goldfinger.
